Drug Interaction Report

Using ziprasidone together with venlafaxine is not recommended. Combining these medications can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with either of these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Using ziprasidone together with hydroCHLOROthiazide can increase the risk of an irregular heart rhythm that may be serious. If your doctor prescribes these medications together, you may need regular monitoring of your electrolyte (magnesium, potassium) levels as well as other tests to safely use both medications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, or fast or pounding heartbeats during treatment with ziprasidone. In addition, you should let your doctor know if you experience signs of electrolyte disturbance such as weakness, tiredness, drowsiness, confusion, muscle pain, cramps, dizziness, nausea, or vomiting. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Talk to your doctor before using potassium chloride together with losartan. Combining these medications may significantly increase potassium levels in the blood. High levels of potassium can develop into a condition known as hyperkalemia, which in severe cases can lead to kidney failure, muscle paralysis, irregular heart rhythm, and cardiac arrest. You may be more likely to develop hyperkalemia while using these medications if you are elderly, dehydrated, or have kidney disease, diabetes, or advanced heart failure. Regular or long-term use of nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen (Aleve) may also increase your risk. It is important that you maintain adequate fluid intake during treatment with these medications. In addition, talk to your doctor to see if you should limit consumption of potassium-rich foods such as tomatoes, raisins, figs, potatoes, lima beans, bananas, plantains, papayas, pears, cantaloupes, mangoes, and potassium-containing salt substitutes. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should seek medical attention if you experience nausea, vomiting, weakness, confusion, tingling of the hands and feet, feelings of heaviness in the legs, a weak pulse, or a slow or irregular heartbeat, as these may be symptoms of hyperkalemia. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Treatment with venlafaxine may occasionally cause blood sodium levels to get too low, a condition known as hyponatremia, and using it with some anticonvulsants can increase that risk. In addition, venlafaxine can cause seizures in susceptible patients, which may reduce the effectiveness of medications that are used to control seizures such as OXcarbazepine. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek medical attention if you experience nausea, vomiting, headache, lethargy, irritability, difficulty concentrating, memory impairment, confusion, muscle spasm, weakness or unsteadiness, as these may be symptoms of hyponatremia. More severe cases may lead to hallucination, fainting, seizure, coma, and even death. Also let your doctor know if you develop seizures or experience an increase in seizures during treatment with venlafaxine. Additionally, because these medications may cause dizziness, drowsiness, and impairment in judgment, reaction speed and motor coordination, you should avoid driving or operating hazardous machinery until you know how they affect you.

Chronic use of drugs known as proton pump inhibitors including pantoprazole can sometimes cause hypomagnesemia (low blood levels of magnesium), and the risk may be further increased when combined with other medications that also have this effect such as hydroCHLOROthiazide. In severe cases, hypomagnesemia can lead to irregular heart rhythm, palpitations, muscle spasm, tremor, and seizures. In children, abnormal heart rhythm may cause fatigue, upset stomach, dizziness, and lightheadedness. A dose adjustment or more frequent monitoring by the doctor may be required to safely use both medications. If you are using an over-the-counter proton pump inhibitor medication such as Prilosec OTC, Zegerid OTC or Prevacid 24 HR, you should follow the directions on the package carefully. Do not use the medication more frequently or for a longer period than recommended on the label unless otherwise prescribed by your doctor.

Alcohol may affect blood glucose levels in patients with diabetes. Both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) may occur, depending on how much and how often you drink. You should avoid using alcohol if your diabetes is not well controlled or if you have high triglycerides, neuropathy (nerve damage), or pancreatitis. Moderate alcohol consumption generally does not affect blood glucose levels if your diabetes is under control. However, it may be best to limit alcohol intake to one drink daily for women and two drinks daily for men (1 drink = 5 oz wine, 12 oz beer, or 1.5 oz distilled spirits) in conjunction with your normal meal plan. Avoid drinking alcohol on an empty stomach or following exercise, as it may increase the risk of hypoglycemia.
